June 1, 2022  |  , , ,

Ultem PEI Polyetherimide thermoplastic component

Ultem Polyetherimide is a material widely used in the aerospace industry.  It is often applied to aircraft components for weight reduction in place of metal parts.  Additionally, since it has a high thermal resistance rating, polymer components have the benefit of evading radar detection in military aircraft.

ULTEM is among the few resins approved for use in the aerospace sector. It outperforms comparable thermoplastics when it comes to resisting creep and does not degrade under repeated mechanical stress. It also holds up well when brought into contact with various fuels, coolants, and lubricants. Its flame-resistance ensures that it meets FAA regulations for flammability.

ULTEM has one of the highest dielectric strengths of any thermoplastic material. It works very efficiently as an electrical insulator. ULTEM also has one of the lowest rates of thermal conductivity, allowing parts machined from ULTEM to act as thermal insulators. ULTEM offers excellent long-term heat resistance with its mechanical and physical properties remaining stable at elevated temperatures.  It is also flame resistant with extremely low smoke generation. ULTEM is FDA and NSF approved for both food and medical contact resistance act and therefore is an excellent choice for aircraft galley equipment such as ovens, microwaves and hot or cold beverage dispensing systems.

Ultem is now widely used in:

  • Personal Service Units
  • Oxygen Panels
  • Ventilation Systems
  • Connectors
  • Cable Ducts
  • Latches
  • Hinges
  • Food Tray Containers
  • Door Handles
  • Interior Cladding Parts

Ultem offers exceptional balance of flame retardancy, low smoke emission and low smoke toxicity making it an excellent candidate for aerospace and aircraft applications.

Fluoropolymers Are A Great Choice For Parts That Must Perform In Unique Conditions

May 19, 2022  |  , , ,

When you need parts that can withstand extreme operating conditions, fluoropolymers may fit the bill. Parts like roofing membranes, fuel tubes, biomedical devices, and wires are all common applications of fluoropolymers.

FEP Fluoropolymer:

Fluorinated ethylene propylene (FEP resin) is a melt-processable fluoropolymer. FEP has low gas and permeability properties, can be extruded in long continuous lengths, and possesses excellent UV transmission rating. FEP is also suitable for use in a biomedical setting and is gamma sterilizable.

All of these attributes make FEP an ideal fluoropolymer for a diverse range of applications from environmental monitoring equipment to medical devices and electronics. Because it is a thermoplastic, FEP is also easily heat-formed, tipped, tapered, flared, and flanged.

PFA Fluoropolymer:

Perfluoroalkoxy (PFA resin) is a melt-processable fluoropolymer that combines many of the best traits of PTFE and FEP. At 500 °F (260 °C), PFA has a higher service temperature than FEP and maintains its mechanical integrity in extreme temperatures even when exposed to caustic chemicals. PFA has greater tensile strength than PTFE and a smoother surface finish than both PTFE and FEP.

PFA’s is a top choice in semiconductor, chemical, oil and gas, aerospace, automotive, pharmaceutical, and medical industries. This fluoropolymer has excellent lubricity, clarity, flexibility, and chemical resistance, making it a versatile choice.

FEP vs PFA Fluoropolymers

FEP and PFA are injection moldable, highly inert, compatible with most organic compounds, have good barrier properties and high continuous use temperatures. They are virtually impervious to chemical, enzyme and microbiological attack and stiffer than PTFE. The non-stick properties of these polymers can also be useful to reduce liquid, gel and powder adhesion. Fluoropolymers in general, have good dielectric properties and are resistant to atmospheric degradation.
While significantly less expensive than PFA, FEP is very difficult to mold due to its low viscosity. However, Performance Plastics has developed proprietary tooling and processes enabling the injection molding of small, thin-walled, complex FEP parts.

• More transparent than PTFE (not injection moldable)

• Better gas and vapor permeability properties than PTFE
• Maximum working temperature 400°F
• Approximately 1/3 the cost of PFA

PFA is significantly easier to mold than FEP, however, it is significantly more expensive.

• Higher continuous service temperature than FEP
• Maximum working temperature 500°F
• Difference in molecular structure gives PFA improved flow, creep resistance and thermal stability.

At Performance Plastics, we are experts in injection molding, specializing in high performance plastics. Our proprietary tool design software, processes and equipment enable us to injection mold components having complex geometries made from challenging ultra, high-performance thermoplastic materials, and reinforced compounds.

Performance Plastics Key Capability –  Net Shape Thermoplastic Peek Seals

May 11, 2022  |  , , , , ,

 
Mating parts providing a fluid or gas seal are critical components in most mechanical systems. We commonly think of them in valves and connector assemblies, but they are also found in pressure vessels, compressors, pumps, motors, engines, transmissions, and almost all mechanical power trains. Seals, especially those that mate to moving parts, have a demanding set of quality requirements. Each application has its own specific needs, but all seals are characterized by tight dimensional tolerances and excellent surface finish.

Our customer wanted to improve the usable life and leakage profile of a valve without absorbing any increase in component cost.  The sealing surface specifications were tightened to 0.0005 inches (12.7 µ) which was key to accomplishing the performance improvements.

The previous supplier of this component was unable to meet the more stringent sealing surface dimensional tolerances “out of the mold” necessitating a finish machining operation to bring the part into tolerance.  However, machining the sealing surface removed the resin-rich surface of the part creating micro-cracks in the surface and exposing reinforcing fibers. Both of these unavoidable consequences of machining negatively impacted component performance, useful life and cost.

Solution

Performance Plastics knew eliminating the machining operation would improve strength, reduce trapped impurities, and lower manufacturing cost.  Our engineering team focused on producing a “true net shape” part directly out of the mold.   Key to accomplishing the customers goals involved leveraging our proprietary, iterative tool design process.  It required making a 3D CT scan of preliminary molded parts measuring, in this case, approximately 1 million critical part dimensions.  This analysis identified minute distortions.  Utilizing internally developed proprietary software, PPL integrated the CT scan data with CAD/CAM software to make exacting mold modifications eliminating the out of tolerance conditions.  This process contributed to producing a best in class “out-of-mold” conforming part.

The manufacturing process also had to be optimized to produce the desired performance results.  Although the material posed molding challenges, PPL decided to direct gate the part at the top to ensure symmetry of material flow throughout the cavity, critical in achieving roundness to the sealing surface.

The results of development program surprised everyone. Performance Plastics was able to achieve  “out of mold” net shape parts with a seal surface capable of meeting sealing ranges of 100 psi to 3,000 psi, with no porosity and consistently meeting dimensional tolerances of 0.0003 inches, or 7.62 µ. Eliminating the need for subsequent finish machining dropped the leakage rate for the valve by 50%, from 1.0 scfm to 0.5 scfm.

Injection Molded Parts for Air Motors

January 6, 2022  |  , , , ,

The ability to mold unique and complex parts is what we do at Performance Plastics. Our engineers are constantly pushing the limits of our machines and material in order to produce complex parts. We excel when using high performance plastics for challenging applications.

Air motors produce continuous rotary power from compressed air. The vanes in the rotor cause the rotor to spin by sliding in and out when air is pushed into the rotor. The force differential created by the unbalanced force of air on the vanes causes the rotor to spin in one direction. Vanes are extremely important when it comes to how the motor performs. The torque of the motor correlates to the vane surfaces and pressure of the air. Vanes undergo a lot of friction wear and pressure, making material choice for this project challenging.

Vanes need to be made from material that have high strength, low creep, resistance to high temperatures, low friction wear and resistant to water and organic compounds. Any deformity or wear in the vane will take away from the torque of the motor. Therefore, we had to choose a high-performance plastic that will be able to handle the pressure of the compression inside the rotor without wearing or hindering the movement of the vane. The only two high performance plastic materials that fit the criteria are PEEK and Torlon®, two materials that we are experts in using at Performance Plastics. The mechanical properties in these high-performance plastics will allow for the vane effectively slide in and out of the rotor without causing damage to the vane.

Injection Molded PFA in the Lithium Ion Battery

December 17, 2021  |  , , , ,

The Lithium Ion Battery industry has begun using more and more plastic parts in their manufacturing processes. Most batteries intended for light vehicle usage now have 50% more plastic materials than they did even 10 years ago.  Some batteries have entirely plastic formulations ranging from the electrolyte (polymeric electrolytes) to the casing.  This is due to the very low weight of plastics as compared to metals. Plastic incorporation in batteries increases the electrolyte efficiency if used in polymeric electrolytes.

Commercially available lithium-ion batteries also use plastics. Plastic components incorporated in batteries include separators, gaskets, and casing components. Plastics have good shock absorbing characteristics and prevent damage to the basic cell unit from minor accidental shocks. Also, plastics such as Teflon® PFA, Ultem® PEI, and PPSU have high temperature resistance, corrosion resistance, and are electrical insulators so they are excellent at preventing short-circuit and “rapid disassembly.”

There has been a major shift from metal to resins in gasket manufacturing. Gaskets can be made from Ultem®, Ryton PPS and Fluoropolymers (PFA plastic) because of high heat resistance, chemical resistance, and ability to mold thin walls (.012”). Plastic parts may also lower the cost of production of batteries and may eventually replace most metallic components of batteries.

Performance Plastics is highly skilled at designing and molding high performance materials such as FEP/PFA, Ultem®, Torlon®, PEEK, POM, and PPS.  We work with our customers to solve technically challenging problems.   We can propose materials to implement part functionality in the design stage of development. We offer manufacturing solutions such as a clean room, the ability to offer direct gating of fluoropolymers, high volume production, visual inspection and automated facilities.

Why Use Torlon®/ PAI for your Applications

November 17, 2021  |  , , ,
Torlon Performance Plastic component

Custom Torlon Performance Plastic Component

Torlon® is a high performance amorphous (non-crystalline) engineering thermoplastic that possesses exceptional physical and chemical qualities.   It is recognized as the highest performing thermoplastic that is still melt processible. Torlon®/PAI is a Polyamide-imide, which are either thermosetting or thermoplastic, amorphous polymers that have exceptional mechanical, thermal, and chemical resistant properties.

Torlon’s® exceptional properties are the result of being transformed from a thermoplastic to a cross-linked thermoset during a curing process. Torlon® is available in glass reinforced and carbon fiber reinforced grades which offer even greater stiffness and enhanced thermal expansion properties. The wear grades offer unmatched performance over a wide range of temperature and PV conditions.

Torlon® can be extruded into shapes and injection molded into intricate custom geometries. It performs well under severe conditions and at continuous temperatures as high as 500° F.  Torlon® possesses remarkable resistance to wear, creep and chemicals, including acids and most organics, which make it ideal for severe environments. Torlon® also has superior electrical and structural strength at high temperatures, excellent radiation resistance, an extremely low coefficient of linear thermal expansion, and exceptional dimensional stability.

Torlon® is the superior choice when applications require extreme high or low temperatures, such as bearings and seals.  PAI polymers offer superior compressive strength and high hardness characteristics that are critical in many applications that demand a high level of wear performance.

Torlon®/PAI polyamide-imides also offer superior toughness or impact strength.  PAI has a high heat deflection temperature and retains higher strength and stiffness at elevated temperatures. With PAI having superior stiffness and a lower coefficient of thermal expansion, this means that PAI has the advantage of better dimensional stability at elevated temperatures. However, PAI does absorb moisture, therefore, this also needs to be considered relative to the potential limitations a lack of humidity control could present with regard to dimensional stability.  PAI has higher tensile and compressive strength in the unreinforced extruded grade which has advantages in some applications.

For more information on Torlon® or other Performance Plastics products, please contact Rich Reed, Vice President of Sales & Marketing at [email protected] or call 440-785-7122.
